A Russian Soyuz rocket carrying NASA astronauts Nick Hague and Christina Koch along with Roscosmos' Alexei Ovchinin lifted off as planned from the Baikonur cosmodrome in Kazakhstan at 3:14 p.m. EDT. The astronauts successfully docked at the International Space Station (ISS) at 9:01 p.m., and they stepped on the ISS at 11:10 p.m., according to NASA.
Koch earned her bachelor's degree in physics and electrical engineering from N.C. State in 2001 and her master's in electrical engineering a year later.
About 100 people gathered on the N.C. State campus Thursday to watch the take off, despite students being out for Spring Break.
"She wanted to be an astronaut, so do about 100,000 other kids, and so her enthusiasm was just absolutely contagious," explained Stephen Reynolds, a professor of 34-years at N.C. State who served as an advisor to Koch while she was a student. "We have wonderful students at N.C. State and they go off and do all types of cool things. But this is as cool as it can get."

Their Soyuz MS-12 spacecraft reached a designated orbit about nine minutes after the launch, and the crew reported they were feeling fine and all systems on board were operating normally. They are set to dock at the space station in about six hours.
On Oct. 11, a Soyuz that Hague and Ovchinin were riding in failed two minutes into its flight, activating a rescue system that allowed their capsule to land safely. That accident was the first aborted crew launch for the Russian space program since 1983, when two Soviet cosmonauts safely jettisoned after a launch pad explosion.
NASA Administrator Jim Bridenstine congratulated the crew on a successful launch. "So proud of Nick Hague for persevering through last October's launch that didn't go as planned," he tweeted.
Speaking at a pre-launch news conference at Baikonur, the crew said they trusted the rocket and fully believed in the success of their mission.
"I'm 100 percent confident in the rocket and the spacecraft," Hague said. "The events from October only helped to solidify that and boost confidence in the vehicle to do its job."
The trio will join NASA's Anne McClain, Roscosmos' Oleg Kononenko and David Saint-Jacques of the Canadian Space Agency who are currently on the space station. They will conduct work on hundreds of experiments in biology, biotechnology, physical science and Earth science.
When one of the four strap-on boosters for their Soyuz failed to separate properly two minutes after their launch in October, Hague and Ovchinin were jettisoned from the rocket. Their rescue capsule plunged steeply back to Earth with its lights flashing and alarms screaming, subjecting the crew to seven times the force of gravity.
Hague emphasized Wednesday that they were well-trained for the emergency.
"The nature of our profession is we spend 90-95 percent of our time practicing what to do when things go wrong," he said. "And so we spend all that time training, running through all those scenarios. And because we do train that way, like in October when things like that happened, we were ready to do what we need to do to come out successfully."
The October failure was the first aborted launch for the Russian space program in 35 years and only the third in history. Each time, the rocket's automatic rescue system kept the crew safe.
A Russian investigation attributed October's launch failure to a sensor that was damaged during the rocket's final assembly. The next crew launch to the space station in December went on without a hitch.
Ovchinin recalled that they felt "more annoyed than stressed" when their rescue capsule touched down in the barren steppes of Kazakhstan. "It was disappointing and a bit frustrating that we didn't make it to the International Space Station," he said.
NASA and Roscosmos praised the crew's valor and composure in the aborted launch and promised to quickly give them a second chance into space.
"We don't accept the risk blindly, we have mitigated it as much as we can, and we always plan to be successful," Hague said.
Ovchinin stressed that the aborted launch in October was an "interesting and very useful experience" that "proved the reliability of the emergency rescue system."
Since the 2011 retirement of the U.S. shuttle fleet, Russia's Soyuz spacecraft have been the only vehicles that can ferry crews to the space station.
NASA, however, is counting on SpaceX and Boeing to start launching astronauts this year. The SpaceX ship Dragon returned Friday from a six-day unmanned demonstration flight to the space station and could take astronauts there on its next flight as early as this summer.
